Connection to DB2 problem

I'm having problems selecting data from a Linked Server pointing ta a UDB DB2 database.
I'm able to connect to the database, however, for some reason I can't read the tables. My queries returns that the table does not exists.
Am I missing something here?
The user db2admin is the database administrator.

Result:
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "IBMDADB2" for linked server "TESTE" does not contain the table ""DB2ADMIN"."TMK0101"". The table either does not exist or the current user does not have permissions on that table.
